Apparently the problem with jumping multiple tracks is not limited to VBR encoded files. I am having a problem with Roger Waters-Radio K.A.O.S. track 7, encoded at CBR 224. It behaves very strange - if I try to seek back, as soon as track 7 starts (< 2 sec or so) it behaves normally and continues seeking into track 6. If I wait until it is 5 or 10 seconds into the track and then seek back, it seeks back to track 6 for a fraction of a second an then skips back to track 5 and continues to seek normally.

I have made the 3 files available at http://24.184.34.6 (temporarily, anyway) in case anyone would like to try to duplicate my results...
